基于多线激光雷达的远控铁路轨道式集装箱门式起重机安全避障系统OA

To address issues such as large blind spots and low obstacle avoidance reliability in traditional rail-mounted gantry cranes,an active 3D obstacle avoidance system based on multi-beam lidar was designed.In this system,a lidar featuring a 50 m detection range,±1 cm accuracy,32-beam scanning capability,and IP67 protection rating is used.By integrating noise filtering,ground segmentation,and Euclidean clustering algorithms for point cloud data processing,it achieves comprehensive three-dimensional perception of the rail environment and real-time obstacle identification.The system implements a hierarchical warning and control mechanism(audio-visual alerts,deceleration,emergency braking)and interfaces with the crane control system for autonomous safety decision-making.Application tests demonstrate that the system can stably detect static and dynamic obstacles within a 30 m range,with response times below 200 ms under rainy,foggy,or dusty conditions,significantly outperforming traditional ultrasonic or 2D lidar solutions.It effectively mitigates collision risks and provides a highly reliable safety solution for the intelligent upgrading of port lifting equipment.
